I read the sticky on contacting Nintendo, I did, detailing my problem and they said they would have to get me to send them my Wii to calculate the damage and fix it.

Therefore before I go to that last resort I want to see if anybody has suffered the same problem as me.
With most of my wii games, when I go to the disc channel and press start, the wii decides to reset back to the wii menu.
I tried the lens cleaning kit, and it made next to no difference.
Any help available?
